The frightening supernatural being created on the internet that has taken on a life of it's own.
On May 31, 2014, 12-year-old Payton Leutner of Waukesha, Wisconsin, was attacked by two friends and stabbed 19 times in an apparent attempted murder. Bleeding from wounds on her arms, legs, and torso, Payton managed to drag herself to the road, where a passing cyclist rendered aid.
The alleged perpetrators, 12-year-old Morgan Geyser and 12-year-old Anissa Weier, confessed under police questioning and admitted they had been planning the attack for months. Their motive: to please the Slender Man.
